Just a couple more Solar videos to come after this one. Teaser: we have it up and running now, and it seems to be working well.

[@petew8388]

Glad you are installing a solar system Ben. I live on a small holding and with crippling power costs at the moment I want to do similar to help keep costs down , so I will watch with interest. Love watching your Range Rover vids as well Ben, I still have a bad parasitic draw with my recently acquired L322, hope yours is sorted now.

[@Bensgarage]

Range Rover seems to be playing ball now, keeping fingers crossed. Yes, power is going to get more expensive next year. It has been a bit of an out lay, and it will take a few years to see the benefit, but we can be independent and not have to rely on edf.

[@panagiotiska1539]

Dear Ben, great video once again. I think you bought very good batteries. Since it's lithium, maybe some adjustment needs to be made regarding the charge or discharge rates on the Growatt? I mean about the percentages. Thank you very much once again

[@jamest5149]

Yep, no separate grounds in the ground… you can make a potential difference between them and get a shock 👍

[@Bensgarage]

I had read that creating a ground loop, would damage the inverter too. So looks like I’m good on all fronts.

[@jamest5149]

A tip,to stop connection issues, torque up correctly all terminals, you can end up with resistance problems or a terminal coming loose 👍

Hi great vid just what i need. Looks like i have the same inverter as you spf 3500 es,i am going to purchase 2x pylontech batteries like you but i was dubious as i wasn't sure if they was compatible. You have reassured me Thank You. Does that communication cable connect into the bms port or the rs 485 port on the inverter.

[@richardkoczy8458]

Great video. Can I ask what was the make and supplier of the rack and do you think it has enough room for 4 of those batteries. Thanks

[@Bensgarage]

I got the rack from Thomann.de it’s made by millennium. Not meant for batteries, you wouldn’t get four in this one, but they do larger ones which probably would. It’s not the strongest, but we don’t move it about, and it’s holding up well so far.

[@ajh8558]

Hi Ben, could you do an update on how it’s going with these batteries? V interested in installing similar. Thanks.

[@zaneswart2371]

Hi Ben! Thank you so much for your video. I do have a question. I have the same batteries but not sure what the ADD / dip switches should be on, any advice? Thank you 🙌

[@Bensgarage]

I have them all set in the up position, not sure if that’s correct, but they seem to be working ok. The BMS is also working, and communication with the inverter all seems to work as well.

[@zaneswart2371]

Thank you Ben! I in the end had my communication cable in the wrong place 😂 I have a goodwe inverter and oh my gosh having so much trouble with it. It’s not picking up the grid now. I have a different growatt setup on our house. Never had any problems, but got a goodwe for free lol, no wonder it was for free 😂

[@philiphawkins5865]

Hi Ben. Great video. I have one Pylontech battery US 3000 and considering adding another. Our one battery charged completely by mid morning when it’s sunny in the summer but in winter it doesn’t charge fully at all making two batteries in winter, when are usage is high, superfluous . Do you reckon the additional battery is worthwhile

[@Bensgarage]

We have the two (want to add more) and they seem to be doing a good job so far. Batteries were at 69% last night before bed, this was after a rainy day, and this morning they were at 42%. So not sure if we could get through the night comfortably with just one. Seem to work well for us in the winter too, also depends how much PV you have coming in. We aim to get more panels up very soon, to catch some winter sun.

[@SafarWIP]

what kind of cabinet you used? About to install the same batterys but in my shed outside, do you think it is all right? A bit cold there but never under 0:) and I can do some insulation for sure there.

[@Bensgarage]

I used a millennium studio rack from thomann.de, it's not rated for the weight of these batteries, but we don't move the cabinet about and it's working well for us. As for the temps, check the instructions, there are specs for operating temps in there.

[@bikeradycbr]

Bugger there chunky batteries!

[@Bensgarage]

They are also bloody heavy.

[@badWithComputer]

The Growatt manual states that there must be a breaker/fuse between battery and inverter. 150A springs to mind but not 100% on size.

[@Bensgarage]

I have seen this, and when clarifying with the company where I bought it, who are also installers, say there is no need. I might add something when we install the second inverter though.

[@rajbryanelectrical653]

Hi Ben On your dip switches you didn't mention it, and programming

[@programconsultant]

Hi Ben. Great video, helped me to set up my batteries. Question - what rack did you use and where could I buy it? Have hard time to get one in Slovakia. Many thanks.

[@Bensgarage]

It's not really made for the weight of the batteries, but I figured once they were in I wasn't going to be moving it about, so should be alright. I also used some wood at the back of the batteries to support a bit of the weight. www.thomann.de/intl/millenium_sr2012_studiorack.htm

[@programconsultant]

Thanks a lot Ben. I ordered it from Tomman and it arrived in the meantime. Take care!!!

[@programconsultant]

Hi Ben. I have two Pylontech US 3000C as you do connected to AESun 5.6 kw invertor. For some reason, every time batteries gets fully loaded (reach 53.5volts as defined in user manual), and sun goes down, the voltage drops to 49 volts in 3to4 hours without anything being connected to it (apparch from inverter) Once it reaches 49 volts its stays stable till next day. Funny is that batteries lights still show fully charged. The figures comes from inverter. Do your batteries behave same way? Or you may have an idea what such dramatic droppage? Appreciate your input.

[@courtmanr]

Hey Ben, I've just received my us5000 and server rack. Am I right in thinking the batteries only attach to the server rack on the front? It seems like an awful lot of weight to only be held on at the front?

[@Bensgarage]

The rack I have, has fittings in the middle to hold some of the weight, I also have the back of the batteries supported with some wood.

[@rishidwadhwa]

Hey Ben , great video . Would love to know what Cabinate you used and how’s it’s holding up ?

[@Bensgarage]

I used this rack in the link, it says it won't take the weight of the batteries, but as I don't want to roll it around on the wheels it seems to be fine. Also I have small pieces of wood at the back supporting the batteries. www.thomann.de/intl/millenium_sr2012_studiorack.htm

[@rishidwadhwa]

@@Bensgarage thanks Ben will check it out .

[@kirenpillay]

Are there any changes required for the DIP switches, or is the link port connection enough for it to know which one is master?

[@Bensgarage]

I have never touched the dip switches, they are set the same as they were in the box. I think the link port defines the master battery and the dip switches only come into play when you have multiple battery banks.

[@grahamesells6539]

Hi Ben, we were told that the first dip switch of the main battery should be up? As there was a communication problem we put them all down, now everything seems to be working. But yours are all down? Any comment?

[@Bensgarage]

I have read that the dip switches are not important, until you have multiple battery banks. Our system is working just fine the way I have them set.

[@Visionery1]

1:50, it seems strange that Victron, one of the premium inverter suppliers, recommend a fuse and isolator between battery and inverter, yet your supplier dismisses this requirement. Yes, Pylontech have an on/off switch, but it needs someone to activate it, what if there's an issue and you're not around. Makes one think, maybe you should go out and buy a fuse/isolator?

[@abelramos8983]

Hi Ben my on grid (no hybrid) inverter got two mmpts ... Now im using one from panels can I load the other one from batterys? Technically i mean (respecting volts amps and all that)

[@sahisa]

After adding 2 new US300c batteries to me my existing 3, do I need to change any settings on the inverter to ensure I am charging to the max 17.75kw capacity.

[@Bensgarage]

If you have communication between you inverter and batteries (BMS), you shouldn't need to change any settings.

[@samrodian919]

Nine comments and I'm first the go thumbs up! How does that bloody work? Lol

[@Bensgarage]

[@themorfill]

Are the batteries just hanging off the front rail of that rack?

[@Bensgarage]

No, there are supports half way along, and I have some bits of wood at the back. Too heavy to rely on the front mounts only.

[@piterex7]

Hello there just quick question what is the maximum voltage you set up on inverters for charging. ? Just asking cos I read on forums that if your battery cut off charging before inverter the extra current have nowhere to go and will definitely burn out the internet. So i fought ok ! But in this situation in this particular model like Growatt what if someone used this inverter as only solar no battery and then if nothing connected solar produced energy to so what it won’t burn inverter ? And one more thing what is the max charging voltage for pylontech ? They are 48v can be charged to 48-56 ?

[@Bensgarage]

Not exactly sure of the charging voltages etc. Just set the inverter up for lithium batteries and the BMS does the rest. As for the inverter burning out with no load, it works the other way round. Solar panels do not push power to the inverter, the inverter pulls power from the panels as and when it's needed. So if you have no load, the inverter will just sit idle.

[@flashback9966]

Hi Ben, can you help? Trying to get information on the 'dry contact' port. I assume this a RJ45. All I want to do is remotely turn on/off the battery. Can't seem to find anywhere on what sort of signal is required for Pins1 and 2.

[@Bensgarage]

Sorry, I have no idea. Mine is hooked up to the inverter and that does all the controlling.

[@flashback9966]

@@Bensgarage Not to worry. Thanks.

[@ellemarta]

Hi Ben nice video well done 👏👏 I trying to do the same but my question it is the battery and Inverter need to be installed in my shed to run cable out into my house .. of course in winter will be cold do I need make sure the battery and inverter will be well protected by cold water.. I hope you understand what I mean thank you...

[@Bensgarage]

A lot depends on which inverter and batteries you go for. My system, Growatt inverter will work from 0 - 55ºc and our pylontech batteries will charge 0 - 50ºc and discharge between -10 - 50ºc and shelf temperature is -20 - 60ºc, They obviously will work better in warmer temperatures.

[@ellemarta]

@@Bensgarage hi Ben thanks for the advice the inverter and battery will be the same what you have because at moment is luck like good and better prices on market value last thing I I need to know if 2x3500 equal 7000 kWh pylontech battery is ok to run into a growatt of 48v 100ah 5000kw sorry to ask I'm new on this and I don't want make mistakes thank you..

[@grahamesells6539]

Could you explain what the white switches on the red panel do,thanks

[@Bensgarage]

Did you get the instructions with your batteries? I never changed mine when I installed it, and it all works fine and communicates with the inverter as it should, might have just been luck. According to the instruction manual. Dip 1: RS485 Baud Rate. 1: 9600, 0: 115200, after changing restart the batteries. Dip 2: CAN terminal resistance on BMS side. 1: NONE, 0: Connected, after changing no need for restart. If single group mode, keep Dip 2 at 0 position. Dip 3 & 4: reversed.

[@FireFlySamson]

Thanks for the video. How long on average do you think it will take to get the money back on 1 battery bank or approx 3.5 kwh?

[@Bensgarage]

There are a lot of variables. But for us, 3.5kWh is one battery, which I can get for €1350. And then it depends on your whole system, as to how much you generate and how much you store or pull from your battery. Our current setup, with six panels, one inverter and two batteries cost us about €4500. So we should see a return on our spending in about six years, going on current electricity prices. As the price goes up, our return length gets shorter.

[@FireFlySamson]

@@Bensgarage Thanks for your answer. I had to discount a battery which I think was faulty and now the one left has stayed at 16% all day despite being sunny.. am using washing machine, tv etc and wondering if the energy is coming from. batterys which is which it hasn't gone up?

[@FireFlySamson]

Also do you need to edit any setting if you take a battery away (or add)? or does it just trickle over

[@Bensgarage]

As I don't know your setup it's difficult to answer your question. On our inverter you set the batteries to lithium and connect the communication cable to the batteries, then the BMS does all the work from there, so if I add a battery or remove one, the BMS takes care of it.

[@FireFlySamson]

@@Bensgarage Can you force charge a battery with low voltage. It says 15% charge on it and 5v but left on all day when sunny and went down 1% so bit worried about it. It was part of two but disconnected the second one

[@bccb491]

hi! Do you connected the bms cable (battery-invertor)? Do you have errors on invertor? A have Growatt with Pylontech (same models) and I don't have the proper communication cable. Can you make a video with the connection and settings of this particular part of the setup? I am very interested of all the process in details. I would appreciate it very much if you would do it! Good luck!

[@Bensgarage]

@@bccb491 I have all the dip switches set in the up position (on both batteries). Never had a problem with them. From what I understand, you don't need to change the switches until you have multiple battery banks.

Does it matter which plus and negative you attach the main (and only) bank? They both say either positive or negative but unsure if you should use left or right matching set?

[@Bensgarage]

Negative are the two on the left and positive on the right, I don't think that it matters which you chose, as long as if you are putting multiple batteries in parallel you don't put neg to pos.

Are most hybrid inverters compatible with pylontech batteries? I have a 48v 3kw SNADI hybrid inverter., previously used with led acid batteries

[@Bensgarage]

Sorry, I don’t know. If the inverter has a communication port and it can talk to the battery bms, then maybe. But I would check with your inverter manufacturer first.

[@splangif]

Hi Ben , My inverter has recently started making a loud buzzing noise - very odd. Only installed the day before and I did just plug in the Wi-Fi dongle before the noise started? Any ideas please I turned it off but doesn’t actually turn off?

[@Bensgarage]

You will have to disconnect all power sources, then it should power off. As in solar pv input and grid if you are connected. There maybe a reset in the menu. Haven’t got my handbook available at the moment, but that’s what I’d try.

[@splangif]

[@paulevans5791]

What do you do if the voltage of the batteries are not balanced

[@Bensgarage]

Some sources suggest that connecting them up, they will balance themselves. I'm not sure about that, you could find the lower voltage battery and just connect that one to bring the voltage up, let it rest so that the voltages match and reconnect them all back up. Mine were the same voltage, or thereabouts. But looking to add more this year and will have to check before I install them.

[@kroozer5215]

will your solar system still work and power the house if the grid goes down for a unlimited amount of time

[@Bensgarage]

Yes, we can be off grid with our system. Only connected to the grid until we add to the system with another inverter. But if the grid went down, we would still have power.

[@kroozer5215]

@@Bensgarage thanks Ben for the reply, why i ask is because we are on the verge of having a solar/batteries installed in a couple of weeks time and have read somewhere that if the grid went down you can only run your solar system until your batteries are basically flat then you would be without power - so this is incorrect ? or do you have to fit something where its isolated from the grid ?

[@Bensgarage]

@@kroozer5215 yes, you will only get power when either the sun is out or you have plenty in your batteries. We only have six panels at the moment, and if the grid went down, we can charge the batteries through the inverter using our generator.

[@ricmrodrigues]

I'm thinking about getting some of these batteries myself, but how to you connect this in such a way that your home pulls from the batteries? How is that setup? I was told by an electrician that I needed some other device and then connect only specific appliances to that, and only those would get powered. Didn't make any sense to me. Why can't this be injected at the "entrance" mimicking the power that comes from the grid, ensuring we don't need to pull as much or at all? Isn't that the whole point? thanks!

[@Bensgarage]

All the priorities are set in the inverter (in out case). I can set parameters for load source, ie solar, battery or grid, then I can do the same for charge source and then I can set when to start and stop charging the batteries from grid power. When the sun is doing it’s thing, we don’t need to worry about grid power. Our system, I have wired up in parallel to the incoming grid distribution board, taken a feed from the old board to the inverter for grid back up, and have nearly all appliances on the new board, just leaving a couple of high load items on grid until we get another inverter (making our system 10kw).

[@ricmrodrigues]

@@Bensgarage in my case the inverter is far away on the garage, nowhere near the main breaker and the grid entry point. Is that a problem? There is a way through though. Not an easy pass! Shouldn't there be an automatic way to choose the right balance between sources depending on how priority? Like during the day sun+grid and night battery for example.

[@Bensgarage]

@@ricmrodrigues Not knowing how your system is wired up, I can't comment. All I can do is explain how our system works. I have it set to power the loads, Solar first, if not enough solar coming in it then pulls from the battery as well and when the batteries get to a set point (user set) then the whole system switches to grid for the loads and charges the batteries back up to the set level. I can also set the charging priorities, which I have set on Solar and utility. Solar charges the batteries to 100%, if the sun is shining. Then if the batteries get down to 20% and there is no sun, it goes to grid charging.

[@ricmrodrigues]

@@Bensgarage I currently have a growatt non hybrid inverter. The growatt hybrid is capable of all that on its own?

[@Bensgarage]

@@ricmrodrigues Yes all that is done in the Growatt SPF5000ES hybrid inverter. I am looking at installing a second inverter which will plug into the original and run in parallel. I can run one as a host and the second as a slave unit, will give me 10kw and then I can likely go off grid.
